The Alpha DSLR-A100 marks Sony's debut into the digital SLR
market and launches its new Alpha brand. Alpha was born from a collaboration
announced back in July 2005 between Sony and Konica Minolta to jointly develop
digital SLRs. Later in January 2006, Konica Minolta announced its withdrawal
from the photo imaging business, transferring various digital SLR technologies
including its anti-shake system and lens mount to Sony.

Now one year after the original announcement, the Sony DSLR-A100
or Alpha 100 has arrived complemented by a wide range of lenses and accessories.
As expected the A100's 'Alpha' lens mount is identical to the previous Minolta
A-type mount, allowing it to work with any existing Minolta A-Type lenses.
Indeed most of the 21 Alpha lenses Sony announced with the A100 are based
on existing Konica Minolta lenses, but revised with new zoom and focusing
grips, along with Sony's branding. There are brand new models though, including
three premium products from Carl Zeiss.

While all the Alpha products for 2006 have already been announced,
Sony promises new releases during 2007 which will no doubt include both bodies
and lenses, and intends to 'challenge the market leader' by 2008. That's fighting
talk, wherever you come from.

Any new arrival in the highly competitive budget digital SLR
market needs to be an impressive proposition, and on paper at least, the Sony
Alpha DSLR A100 certainly delivers the goods. Sony's sensibly taken the best
aspects of Konica Minolta's technology including the built-in Anti-Shake mechanism,
lens mount, exposure system, and user interface, and added it's own expertise
in CCD sensors, image processing and LCD screens.

The result is a 10.2 Megapixel compact digital SLR with built-in
anti shake capabilities which work with every lens you attach, an anti-dust
system, long life battery, advanced image processing and a nice large LCD
monitor. That's a pretty impressive spec, considering the kit with 18-70mm
lens has an RRP of UK £699 or US $999. Lets put it this way, it's much
more than a Konica Minolta 5D with a new CCD sensor, and already a serious
challenge to Canon's market-leading EOS-350D.

The Sony Alpha DSLR-A100 certainly sounds good in theory, but
how does it perform in practice? In our in-depth review we'll take a look
at this new contender and compare it against immediate rivals like the Canon
350D and Sony's own Cyber-shot DSC-R1, along with Nikon's higher-end D200,
which after all, sports essentially the same CCD sensor.
